How to Install Linux Kernel 4.18 in Ubuntu, Linux Mint

Last updated: August 13, 2018

Linux Kernel

Linus Torvalds finally announced the release of Linux Kernel 4.18 yesterday afternoon. He wrote in lkml.org:

It was a very calm week, and arguably I could just have released on schedule last week, but we did have some minor updates. Mostly networking, but some vfs race fixes (mentioned in the rc8 announment
as “pending”) and a couple of driver fixes (scsi, networking, i2c). Some other minor random things (arm crypto fix, parisc memory ordering fix). Shortlog appended for the (few) details.

Some of these I was almost ready to just delay to until the next merge window, but they were marked for stable anyway, so it would just have caused more backporting. The vfs fixes are for old races that are
really hard to hit (which is obviously why they are old and weren’t noticed earlier). Some of them _have_ been seen in real life, some of them probably need explicit help to ever trigger (ie artificial delays
just to show that “yes, this can actually happen in theory”).

Changes in kernel 4.18 include:

  • Initial support for the Qualcomm Snapdragon 845 SoC.
  • Various power management improvements to AMDGPU
  • Initial NVIDIA GV100 Volta support within Nouveau DRM driver
  • 32-bit ARM finally gets mitigated for Spectre V1/V2
  • Various new sound chips support
  • USB 3.2 and USB Type-C improvements.
  • And many other changes.

How to Install Linux Kernel 4.18 in Ubuntu:

There a few tools, e.g., UKTools and Ukuu, make it easy to install the latest Kernel in Ubuntu.

You can also manually download the Kernel 4.18 Ubuntu binary packages at:

Download Kernel 4.18

Depends on your OS type, download and install the packages in turns:

  1. linux-headers-4.18.0-xxxxxx_all.deb
  2. linux-headers-4.18.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb
  3. linux-modules-4.18.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb
  4. linux-image-xxx-4.18.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb

Select generic for common system, and lowlatency for a low latency system (e.g. for recording audio), amd64 for 64bit system, i386 for 32bit system, or armhf, arm64, etc for other OS types.

Also you can download and install the kernel binaries via terminal commands:

For 64-bit OS:

cd /tmp/

wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.18/linux-headers-4.18.0-041800_4.18.0-041800.201808122131_all.deb

wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.18/linux-headers-4.18.0-041800-generic_4.18.0-041800.201808122131_i386.deb

UKTools – Another Tool to Install the latest Linux Kernels in Ubuntu

Last updated: August 10, 2018

Linux Kernel

There’s already a graphical tool called Ukuu which make it easy to install the latest Linux Kernels in Ubuntu and Linux Mint.

Today I’m going to show you a new command line tool called UKTools which provides:

  • uktools-upgrade, one command to install the latest Linux kernel (stable) from kernel.ubuntu.com.

  • uktools-purge, one command to remove old kernels, the first and the last two are excluded.

The tools also support cron jobs to automatically run upgrade and/or purge scripts.

NOTE that the mainline kernels are provided by Ubuntu Kernel Team for testing and debugging purposes. They are not supported and are not appropriate for production use. You should only install these if they may fix a critical problem you’re having with the current kernel. Read more about mainline kernels.

How to Install UKTools in Ubuntu:

The application does not has any Ubuntu binary at the moment. However, it’s easy to compile it from the source.

1. Open terminal (Ctrl+Alt+T) and clone the source via command:

git clone https://github.com/usbkey9/uktools && cd uktools

2. Then compile and install it via command:

make

The setup runs automatically if it’s installed successfully.

Uninstall:

Keep the uktools folder in your user root directory, so you can re-run UKTools setup, or remove the command line tool via command:

cd ~/uktools/ && make uninstall
